  Hi Steve,
  Better wait till Dave Thompson or Clive Gimson answers for a GT6. For a spit I aim to end up with 25 or 26 psi as a final pressure with the tyre hot, this means 20 psi in left front and left rear 22 1/2 psi right front and 23 1/2 psi right rear as starting pressures. I used this setup at Mallory last weekend and finished the first race with 25 psi all round and the second race with 26 in both left tyres and 25 1/2 in both right tyres.
  
  Hope this info is of some help, have a great track day.

    Can't argue with Captain Scarlet's answer.
    
    You are corrrect that there are so many variables it's not possible to say what pressure you should start at....depends on the air temp, track temp, humidity, camber, spring rates, driving style, circuit, weight of car, etc etc etc. Aim for 25 PSI hot and you won't go far wrong. Just note your starting pressure for each tyre, put in a few good laps to get the temp up and measure again. It's trial and error I'm afraid. Good luck, have fun and keep it shiney side up.

      Thanks Ralph/Dave,
      Looks like my next investment is a good accurate tyre pressure gauge!
      cheers
